Fair point, Cornwall. I guess that's why David Eades is a good choice, because he can effectively do both.
Yep - David Eades was a Sport Correspondent for a number of years.
As for the argument about sending presenters/non-sports reporters - there are a number of things to consider.
Sports reporters/correspondents are good at match reporting, and in some cases the wider team reporting role. What they may not have the experience to do is link between reports in a presentation role, and provide decent contextual background reporting on the event, it's non-sporting impact etc. itself.
There is also the issue of location to consider. The matches aren't all taking place in the same stadium or a couple of stadia in the same town - they are taking place across the whole country, from stadia hours away from each other, so you need more people than you might think to provide decent coverage. You may end up cutting match reports in one location, but having presentation facilities in a different location (which is cheaper than having editing reports on site at every presentation location?)
